First 100 laparoscopic surgeries in a predominantly rural Nigerian population: a template for future growth

Surgical Practice in Resource-Limited Settings: Perspectives of Medical Students and Early Career Doctors: A Narrative Review

Introduction

Surgical practices in low-resource countries often fail to meet established standards. Both doctors and medical students have limited exposure to surgical cases, which hinders training and the development of surgical specialization. This study highlights the current state of surgical practice from a trainee's perspective, explores existing gaps in training and capacity building, and recommends practical solutions.

Methods

We conducted a literature search on PubMed, Google Scholar, and other scientific databases using search terms such as "surgical practice," "doctors' perspectives in surgical practice," "surgery in low- and middle-income countries," and "solutions to surgical inadequacy." We included studies published from 2015 to 2024, with exceptions for a few highly relevant studies published prior to 2015.

Results

We outline the limitations identified in the literature concerning surgical training and healthcare in low- and middle-income countries. Many centers lack adequate infrastructure, human resources, and training. These challenges negatively affect the skills and quality of surgical care. However, some centers demonstrate that surgical practice is feasible through collaboration with institutions established in higher-income contexts.

Conclusion

Telesurgery, task shifting and sharing, high-impact, low-cost surgeries, and collaborations with more developed health systems could effectively bridge the gap in surgical availability in LMICs.

Trends and Outcomes of Laparoscopic Surgery in Low-Resource Settings: Lessons From Two African Healthcare Systems-A Narrative Review

Introduction

Laparoscopic surgery (LS) has been a promising development in surgical practice globally ever since its introduction. LS has exhibited many an advantage, including bettering patient outcomes, lowering the risk of postoperative infection, and displaying economical affluence. However, its implementation in the African continent still faces various challenges. In this review, we investigated the status of laparoscopic surgery integration in Africa.

Objectives

In this review, we aimed to investigate the challenges posed by the implementation of LS in low resource countries as well as critically evaluating initiatives and their impact within said domiciles. We also provide recommendations that may assist in LS prosperity in these settings by focusing efforts on improving training and financial incentives.

Methods

A comprehensive literature review was conducted to garner up-to-date evidence concerning the fate of LS adoption in low- to middle-income countries. This comprised the analysis of different case studies from countries including Nigeria and Botswana, and investigated relevant recommendations and policies provided by other African countries.

Results

Various challenges face the implementation of LS in countries with low resources comprising poor infrastructure, scarce training programs, and expert training personnel alongside financial boundaries. The adoption of LS in Africa has proved its benefits in improving patient outcomes and reducing hospital admissions. From a perspective of policy, it is crucial to sustain strong ties amongst institutions, stressing the importance of dynamic collaboration and locally tailored policies.

Conclusion

It has been demonstrated that LS implementations in African nations lower infection rates and expedite recovery. A strong collaboration between governments, stakeholders, and healthcare providers is fundamental for successful integration of LS. Such extension in low-resource environments may be achieved by providing proper training programs, funding infrastructure and equipment, and fostering effective financial initiatives.

A Prospective, Observational Cost Comparison of Laparoscopic and Open Appendicectomy in Three Tertiary Hospitals in Nigeria

BACKGROUND

The clinical benefits of laparoscopic appendicectomy are well recognized over open appendicectomy. However, laparoscopic procedures are not frequently conducted in many low-and middle-income countries (LMICs) for several reasons, including perceived higher costs. The aim of this study was to assess the feasibility and cost of laparoscopic appendicectomy compared to open appendicectomy in Nigeria.

METHODS

A multicenter, prospective, cohort study among patients undergoing appendicectomy was conducted at three tertiary hospitals in Nigeria. Data were collected from October 2020 to February 2022 and analyses compared the average healthcare costs at 30 days after surgery. Quantile regression was conducted to identify variables that had an impact on the costs, reported in Nigerian Naira (Naira) and US dollars ($), with standard deviations (SD).

FINDINGS

This study included 105 patients, of which 39 had laparoscopic appendicectomy and 66 had open appendicectomy. The average healthcare cost of laparoscopic appendicectomy (147,562 Naira (SD: 97,130) or $355 (SD: 234)) was higher than open appendicectomy (113,556 Naira (SD: 88,559) or $273 (SD: 213)). The average time for return to work was shorter with laparoscopic than open appendicectomy (mean: 8 days vs. 14 days). At the average daily income of $5.06, laparoscopic appendicectomy was associated with 9778 Naira or $24 cost savings in return to work. Further, 5.1% of laparoscopic appendicectomy patients had surgical site infections compared to 22.7% for open appendicectomy. Regression analysis results showed that laparoscopic appendicectomy was associated with $14 higher costs than open appendicectomy, albeit non-significant (p = 0.53).

INTERPRETATION

Despite selection bias in this real-world study, laparoscopic appendicectomy was associated with a slightly higher overall cost, a lower societal cost, a lower infection rate, and a faster return to work, compared to open appendicectomy. It is technically and financially feasible, and its provision in Nigeria should be expanded.

Barriers to training in laparoscopic surgery in low- and middle-income countries: A systematic review

Laparoscopic surgery has the potential to improve care in resource-deprived low- and-middle-income countries (LMICs). This study aims to analyse the barriers to training in laparoscopic surgery in LMICs. Medline, Embase, Global Health and Web of Science were searched using ‘LMIC’, ‘Laparoscopy’ and ‘Training’. Two researchers screened results with mutual agreement. Included papers were in English, focused on abdominal laparoscopy and training in LMICs. PRISMA guidelines were followed; 2992 records were screened, and 86 full-text articles reviewed to give 26 key papers. Thematic grouping identified seven key barriers: funding; availability and maintenance of equipment; local access to experienced laparoscopic trainers; stakeholder dynamics; lack of knowledge on effective training curricula; surgical departmental structure and practical opportunities for trainees. In low-resource settings, technological advances may offer low-cost solutions in the successful implementation of laparoscopic training and improve access to surgical care.

Use of commercial mesh for hernia repair in a low resource setting: experience after 500 cases

BACKGROUND

The use of mesh has revolutionized the management of hernias in many parts of the world. There is, however, limited experience on its use in sub-Saharan Africa. This study describes a single hospital experience after 500 cases of mesh hernia repairs in a sub-Saharan African country.

METHODS

We reviewed the records of the first 500 cases of abdominal wall hernia operations performed using commercial mesh since year 2007. Socio-demographic characteristics, hernia type, method of repair and outcome data were analyzed and presented as descriptive statistics.

RESULTS

The first 500 cases of mesh hernia repairs were performed between 2007 and 2017 during which a total of 1,175 hernia operations were carried out, mesh repair accounting for 42.5% of the total. There was a progressive rise in the uptake of mesh repairs over time, with mesh repairs overtaking tissue based repairs in the last few years of the review. Inguinal hernia was by far the commonest indication for mesh use (80.4%), followed by incisional hernia (9%). Polypropylene mesh was the most common type of mesh used in about 96.2% of cases. Overall, there were seven recurrences (1.4%) at a mean follow-up period of 15.3 months (1-108 months) CONCLUSION: In spite of resource limitations, the use of mesh for hernia repairs continues to rise and has overtaken tissue-based repairs in a sub-Saharan African setting. Results show good outcomes justifying continued use.

Incisionless fluorescent cholangiography (IFC): a pilot survey of surgeons on procedural familiarity, practices, and perceptions

BACKGROUND

Incisionless fluorescent cholangiography (IFC) has recently been proven feasible, safe, and efficacious as an intraoperative procedure to help identify extrahepatic bile ducts during laparoscopic cholecystectomies (LC). We conducted a pilot survey of 51 surgeons attending an international conference who perform endoscopic cholecystectomies to identify their typical LC practices, and perceptions of IFC.

METHODS

An international panel of ten IFC experts, all with > 500 prior IFC procedures and related research publications, convened during the 4th International Congress of Fluorescence-Guided Surgery in Boca Raton, Florida in February 2017. The panel was charged with developing questions about LC practices and experience with IFC, and perceptions regarding its advantages, barriers to use, and indications. These questions then were asked to other congress attendees during one of the didactic sessions using an online polling application. Attendees, who ranged from zero to considerable experience performing IFC, accessed the survey via their portable devices.

RESULTS

Of the 51 survey participants, 51% were from North America; 77% identified themselves as general/minimally invasive surgeons, and roughly 60% performed under 50 cholecystectomies/year. Only 12% performed routine intraoperative cholangiography (IOC), while 72.3% routinely performed critical safety reviews. Thirty-five percent estimated that their institution's laparoscopic-to-open surgery conversion rate was > 1% during LC. Roughly 95% of respondents felt that surgeons should have access to a noninvasive method for evaluating extrahepatic biliary structures; 84% felt that the most advantageous characteristic of IFC is the lack of any biliary-tree incision; and 93.3% felt that IFC would have considerable educational value in surgical training programs; and 78% felt that any surgeon who performs LC could benefit.

CONCLUSIONS

Surgeons who participated in our survey overwhelmingly recommended the routine use of IFC during laparoscopic cholecystectomy as a complimentary imaging technique. Prospective randomized clinical trials remain necessary to determine whether IFC reduces the incidence of bile duct injuries and other LC complications.

Affordable Laparoscopic Camera System (ALCS) Designed for Low- and Middle-Income Countries: A Feasibility Study

BACKGROUND

Minimally invasive surgical techniques (MISTs) could have tremendous benefits in resource-poor environment. There is growing interest in MISTs in most low- and middle-income countries (LMIC), but its adoption has remained limited; this is largely due to high cost of the initial setup, lack of technological backup and limited access to training among others. An affordable laparoscopic setup will go a long way in improving access to MISTs.

METHODS

A common zero degrees 10 mm scope is attached on the camera of a low-price smartphone. Two elastic bands are used to fix the scope right in front of the smartphone's main camera; alternatively, a low-cost camera coupler can be used. The device is covered with sterile transparent drapes and a light source connected with a fiber-optic cable for endoscopic use. The image can be seen in real time on a common TV screen through an HDMI connection to the smartphone, with a sterile drape.

RESULTS

We were able to perform the five tasks of the Fundamentals of Laparoscopic Surgery curriculum, using our vision system with proficiency. In a pig model, we performed a tubal ligation to simulate an appendectomy and we were able to suture. No major differences were measured between the two connection systems.

CONCLUSIONS

A low-cost laparoscopic camera system can benefit surgeons and trainees in LMICs. The system is already attractive for use during training, but further studies are needed to evaluate its potential clinical role in LMICs.

General surgical services at an urban teaching hospital in Mozambique

BACKGROUND

As surgery becomes incorporated into global health programs, it will be critical for clinicians to take into account already existing surgical care systems within low-income countries. To inform future efforts to expand the local system and systems in comparable regions of the developing world, we aimed to describe current patterns of surgical care at a major urban teaching hospital in Mozambique.

METHODS

We performed a retrospective review of all general surgery patients treated between August 2012 and August 2013 at the Hospital Central Maputo in Maputo, Mozambique. We reviewed emergency and elective surgical logbooks, inpatient discharge records, and death records to report case volume, disease etiology, and mortality.

RESULTS

There were 1598 operations (910 emergency and 688 elective) and 2606 patient discharges during our study period. The most common emergent surgeries were for nontrauma laparotomy (22%) followed by all trauma procedures (18%), whereas the most common elective surgery was hernia repair (31%). The majority of lower extremity amputations were above knee (69%). The most common diagnostic categories for inpatients were infectious (31%), trauma (18%), hernia (12%), neoplasm (10%), and appendicitis (5%). The mortality rate was 5.6% (146 deaths), approximately half of which were related to sepsis.

CONCLUSIONS

Our data demonstrate the general surgery caseload of a large, academic, urban training and referral center in Mozambique. We describe resource limitations that impact operative capacity, trauma care, and management of amputations and cancer. These findings highlight challenges that are applicable to a broad range of global surgery efforts.
